TARGET-BULLET.

To all whom it may concern Be it known that I, ALBERT B. GULLY, acitizen of the United States, residing at Bridgeport, county ofFairfield, State of Connecticut, have invented an Improvement inTarget-Bullets, of which the following is a specification.

This invention has for its object to provide a non-jacketed bulletespecially adapted for short range target shooting, which, owing tospecial details of construction hereinafter to be described, willproduce better targets than has been possible with any bullet heretoforeproduced, will not tear the target but will cut a round hole therein,will be self-centering in the bore of a gun barrel should it happen tobe loose in the cartridge shell and will effectually clean the groovesof the bore and keep them clean. lVith these and other objects in view,I have devised the novel target bullet which I will now describe,referring to the accompanying drawings forming a part of thisspecification, and using reference characters to indicate the severalparts.

Figure 1 is an elevation of my novel bullet; Fig. 2 a longitudinalsection thereof, also showing an additional lubricating groove; Fig. 3 afront end elevation of the bullet after leaving the gun barrel; Fig. 4 alongitudinal section of the rear end of a gun barrel showing a cartridgewith my novel bullet in place therein; Fig. 5 a longitudinal section ofa portion of the bore of a gun barrel showing the bullet during itspassage therethrough, and Fig. 6 is an illustration of a target whichhas been hit by an ordinary bullet and also by my novel target bullet.

10 denotes a gun barrel, 11 the grooves of the bore, 12 the lands, 25the chamber, 13 the shell of the cartridge and 14 my novel bullet whichis made of lead or an alloy of lead and is not jacketed. My novel bulletcomprises a heel 15, a body portion 16 and a tip 17. The length of mynovel bullet may vary from one and one-half to two and one-half timesthe caliber as variations from a length of twice the caliber, which Ifind very satisfactory in use. The body of the bullet is cylindrical andis provided with the usual lubricating grooves 18. The heel is ofreduced diameter and may or may not be rounded at its rear end. The tiptapers slightly in a straight line from its Specification of LettersPatent.

intersection with the body to the forward end, which is flat across, asat 19, and is provided with a central recess or cavity 20 having aninclined wall. The depth of the recess is not of the essence of theinvention but depends upon the length and diameter of the bullet and isso proportioned as to give perfect balance to the bullet.

An essential feature of the bullet is that it is fiat across its forwardend as distinguished from having any point whatever, the thickness,however, of the wall at the forward end is immaterial, it being simplynecessary to insure sufiicient stiffness to prevent deformation of thebullets in handling. The tip may or may not be provided with anadditional lubricating groove 21, as shown in Fig. 2. I

Another essential feature of my novel bullet is that the diameter at theforward end of the tip corresponds substantially with the diameter ofthe gun barrel from which it is to be fired, at the tops of the lands,and the diameter at the rear end of the tip corresponds substantiallywith the diameter of the gun barrel at the bottom of the grooves, sothat while the shell and the body of the bullet fit the chamber withmerely a close fit as usual, pressure must be applied to the rear end ofthe cartridge to force the tip of the bullet into the bore. The bulletis easily seated, however, owing to the fact that it is relatively soft.The elfect of forcing the tip of the bullet into the bore is to causethe lands of the bore to form corresponding grooves in the bullet, whichare indicated by 22 in Fig. 4. When the bullet is fired, the effect ofthe resistance of the air owing to the recess in the tip is to expandthe tip outward so that still deeper grooves are formed in the bulletwhich are indicated by 23 in Fig. 5 and which correspond with the landsof the bore, leaving ribs 24 between the grooves 23 which correspondwith the grooves of 1 the bore and fill said grooves and also leavingthe bullet supported in the barrel from end to end so that deflection ofthe bullet (keyholing, as it is called) is avoided. These ribs upon thebullet efiectually clean the grooves of the bore and keep them clean solong as my novel bullets are used, see Fig. 5, in which the dirt in thegrooves of the bore, which is scraped up and forced out by my novelbullet, is indicated by 26.

other important advantage resulting from the taper ,ofthe tip inconnection with its slightly greater diameter than the bore of thegun'barre'l'from which it is to be fired is to insure that it will seatitselfcentrally in the bore, even though it may be loose in thecartridge shell, a condition that frequently happens in small calibercartridges.

r The vitally important result, however, -secured by my novel bulletis'its extreme accuracy in short range shooting. My novel bullet doesnot tear'a paper target but cuts v ,or'dri-lls round hole in it ofappreciably greater diameter than the caliber.

The reason for this will bereadily understood from Fig. 3, which see inconnection with Fig.6. It must be borne in mind that'owlng to its taperand its greater diameter than the lands of the bore, the bullet-issureto is provided with a cavity or recess, the resistance ofthe air willexpand the forward end of the bullet into the grooves of the'bor'eformlng ribs which not only-scrape the grooves of the borerendering it unnecessary to stop to clean'it, but also increase the actlVB or-operatlve diameter of the bullet when it-strikes the target, sothat there can beno te'aringof the target but in fact a round holeisdrilled or cut inthe targetby the rapidlyrotatingbullet. In fact it isfre- 35-quent with my novel bullet to cut sharply.
